Misterio first began training to be a boxer, but after his body got bigger, he took a lot of bumps and lost some of his punching ability. When his trainers told him that he could not still punch hard, they told Misterio about wrestling. His brother soon began to take him to train for professional wrestling. On the sixth of January 1976, Misterio finally made his debut as a wrestler on a show called "Day of the Kings", or Día de los Reyes. Misterio appeared at
World Championship Wrestling's
Starrcade 1990 pay-per-view event where he teamed with Konnan and competed in the "Pat O'Connor Memorial International Cup" representing Mexico. In the first round the team defeated
Chris Adams and
Norman Smiley representing the United Kingdom, but lost to
The Steiner Brothers in the second round.
Training In 1987, Misterio opened a gym with
Negro Casas and Super Astro. His first class included future international superstars such as
Konnan,
Psicosis,
